CGAL users discussion list

Hi,

I work with the CGAL library to compute a bounded voronoi diagram for my 
academic research project.
I use the Delaunay_triangulation_2 class, the Voronoi_diagram_2 class, the 
Min_sphere_of_spheres_d class et other functions like "intersection".

I would like to write an article about my subject but I need to know the 
computing precision. I use C++ double type and I would like to know what is 
the precision that CGAL can ensure?
I work with real number (in double) in the interval [0,1], so how many 
figures after the comma without precision's error can I publish? 

Thanks a lot,
